size plankton may damage the net or sometime misleads the abundance patterns of
other gelatinous zooplankton which entangled with these scyphomedusae, hence
they were studied by direct observation and the specimens were caught by scoop
net or bucket. So assessing the abundance patterns of these groups
(Scyphomedusae) by specially designed net or also by fishing net operations may
be suitable.<o:p></o:p></span></p><br><div><font color="#0000bf"><div><font color="#0000bf">P.Ezhilarasan</font></div> <div><font color="#0000bf"></font> </div> <div><font color="#0000bf">Research scholar</font></div> <div><font color="#0000bf">Centre of Advanced Study in Marine Biology</font></div> <div><font color="#0000bf">Annamalai University</font></div> <div><font color="#0000bf">Parangipettai - 608 502</font></div> <div><font color="#0000bf">Tamil Nadu, SouthIndia </font></div> <div><font color="#0000bf">Email - ezhil_pathy@yahoo.co.in</font></div></font></div></td></tr></table><br>
